LOL
I want one that I can drive on the street again.
I got the "bigger is better" bug out with this jeep.
A buddy of mine picked up an 89 4 door xj 4.0 with auto trans and a 231 transfercase for $150. Im trying to talk him into selling it to me.
And since I already know what I want out of the next one I wont be building it in steps and replacing things two or three times so itll turn out much cleaner, especially since I pretty much learned how to weld on this jeep.
Ill keep posting in here but I'll start a new thread for the new jeep when I get one. Im thinking of starting to do some fab work for people to fund the next jeep.

Yesterday I pulled my old power steering pump off and the old hoses. The old hoses were rated for 250 psi, I figured they would be fine since they are on the low pressure side of the pump... Not really.
So I went to Hesperia Hose and had some new hoses made for a fluid cooler I bought from summit. http://www.summitracing.com/parts/der-13317/overview/
This one barely fit behind the grill, which is perfect because I wanted the largest cooler I could fit. It also has -6 AN fittings which meant the hoses thread onto the cooler instead of using hose clamps.
I feel a lot more confident in this new setup. The new hoses are rated for 4500 psi.
This cooler will fit behind the grill of any xj without modifications. Just route the cooler in line between the steering box and the resivior on the steering pump and this will fix any steering issues.
I also took the pump out to mod it and increase the flow of fluid. I did this because my steering was slow after putting the hydraulic ram on. If I wanted to quickly counter steer you would have to wait for the pump to catch up. This would make the steering wheel have resistance if you tried to turn quickly.
Pump out of the truck. First I ran the pump through my solvent tank to clean it up.
Then Pull the two clips off and the resivior comes right off.


This pic shows where the fitting is that needs to be removed and drilled out. The fitting is already taken out in this pic

You can see the fitting, the piston, and the spring in this pic.
The fitting was drilled to 5/32, which is about the largest you want to go.
The spring was stretched to 2 inches.
I pulled the piston apart, West Texas off-road says that you can take the shim out of the piston when you pull it apart which increases bypass pressure. But they also mention that they have blown seals in the box by taking shims out.
So I took the shim and filed it down so it is about half as thick as stock.
The shim is located in the piston, which has a nut on the bottom that you take off to disassemble the piston.

I've always wanted a 2wd/ax15/8.8/32" tire/ 4.6L stroker for a daily driver. just for fun. but I wised up and got a honda instead.
awesome little write up. that's exactly the next mod I had in mind but the way westtexasoffroad tried to explain it over the phone I didn't feel very confident about what I was doing. gonna have to copy you

If you have any questions ask me on here. I was thinking of doing a little write up on here too.
I went off of their website, once I pulled mine apart it was a lot more simple than it seemed at first.

I was hoping to find a newer xj like a late 90s. But if I can get this xj from my buddy for what he has into it ill have to do it.
Itd be an 89 xj, 4.0 renix, aw4 trans, 231/231 dual cases, Dana 30 with the reid 30/44 conversion knuckles 488 gears, 9 inch rear with 6 lug hubs to match the front 44 outers. 4 inch RE springs, 35 inch MTR kevlars. Itd make a great big bear and rubicon type rig.

The hydro assist is awesome, especially considering how much $ is in it, about $150 total. Be sure to drill out the steering pump or the steering Wil be ridiculously slow.

I didn't even try that with the 40s lol.
I used 3/8 pipe fittings instead of 1/4 which might have helped with the fluid flow to the ram.
Atmos what ram are you using?
